Yes, I am currently building a SIP security proxy (SSP) module that 
uses the dialog modules callbacks to track the SIP dialog life span. 
Also we will be implementing SIP Session Timer support (SST) soon on 
top of the new dialog module.

Here is a snippit from my openser.cfg.m4 file that uses the dialogs in 
the SSP:

...
modparam("dialog", "dlg_flag", FLAG_DIALOG)
...

route {
...

if (method=="INVITE" || method=="ACK") {
	setflag(FLAG_DIALOG);
	t_on_reply("ONREPLY_RELAY");
	ifelse(DEBUG_MODE, `ON', `xlog("L_INFO", "[$mi] loose_route() set 
dialog flag, set t_on_reply(ONREPLY RELAY)\n");', `')
}
...

Now in the dialog module the dlg_create callback is called in the SSP 
that I registered so I can look at the INVITE message.

The registering of callbacks is done just like the tm module so I will 
not include an example. The real secret is knowing when to set the 
DIALOG flag in the openser.cfg :-)

Hope this helps,
